I think a good "white Paper" would be to discuss what I had to do differently to get around problems. Such as the special oiling system of a KB block usually feeds the lifter galleys (extra cost gun drilling) from a groove cut around the #5 cam bearing, but if you increase the cam bearings to 55 MM roller bearings you loose the oil feed channel. Then what do you do? Maybe I'll write an article about surprises of building a big block Mopar engine with aftermarket parts.
